Non-invasive minimally invasive surgery navigation system

Abstract

The invention belongs to the technical field of medical apparatus and instruments and particularly discloses a non-intrusive minimally invasive operation navigation system. The system comprises a pre-operation data module, an intra-operation data module, a positioning module and a navigation module. The pre-operation data module is respectively connected with the intra-operation module and a the navigation module. The positioning module is connected with the navigation module. The intra-operation module comprises a positioner array, a tracker, a pose encoding module and a pose lookup table which are sequentially connected. The positioner array comprises at least three pose positioners. By the system, intrusive equipment is not needed to assist operation navigation. Due to the fact that dynamic data of a patient is collected before an operation, generated modeling data is more accurate, and precision of the navigation provided for doctors is higher. The system further has the advantages that no radiation harmful to human bodies is generated, system cost is lowered while harm of minimally invasive operations to the doctors is relieved, and popularization of the minimally invasive operations is facilitated.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of medical devices, in particular to a non-interventional minimally invasive surgery navigation system. [0003] 【Background technique】 [0004] The human body is an elastic body that changes in real time, and various organs and lesions will move in real time. Clinically, doctors need a surgical navigation system to present relevant information during surgery in real time. The computer-aided surgery system is an advanced medical device that first entered into clinical application in developed countries in Europe and the United States in the early 1990s to provide surgeons with surgical navigation. The surgical navigation system accurately corresponds to the patient's anatomical structure on the operating table with the patient's pre-operative or intra-operative image data During the operation, the surgical instrument is tracked and the position of the surgical instrument is updated and displayed on t...

Problems solved by technology

[0005] At present, there are two main types of surgical navigation systems used clinically: one is to rely only on preoperative CT and MRI images for intraoperative navigation. The problem with this type of surgical navigation system is that it is difficult to track and reflect the elastic human body in real time. For tissues or organs, the preoperative medical imaging data cannot completely match the actual situation during the operation

However, the interventional navigation of the operation by the machine vision module with the endoscope as the main body needs to open the interventional wound on the patient's body, which is not in line with the original intention of minimally invasive surgery to cause minimal harm to the patient, and its impact on the operation of the organ is Unknown; in the operation that requires the endoscope to be guided in the natural cavity, the original shape of the corresponding organ will be destroyed, resulting in a difference from the initial information of the modeling and resulting in errors; most importantly, interventional devices such as endoscopes It will affect the space for the operation, and may even interfere with the doctor's normal operation
